no-vitest-coverage-enabled-false-with-thresholds

Disallow configuring non-empty test.coverage.thresholds while test.coverage.enabled is set to false.

Rule catalog ID: R046

Targeted pattern scope

vitest.config.*
vitest.workspace.*
vite.config.* when Vitest coverage is configured
same coverage scope containing enabled: false and non-empty thresholds

What this rule reports

This rule reports contradictory coverage settings where thresholds are configured but coverage is explicitly disabled.

Why this rule exists

Thresholds represent coverage quality gates and are meaningful only when coverage runs. Keeping contradictory settings out of shared config avoids confusion and dead configuration.

❌ Incorrect

import { defineConfig } from "vitest/config";

export default defineConfig({
    test: {
        coverage: {
            enabled: false,
            thresholds: {
                lines: 90,
            },
        },
    },
});

✅ Correct

import { defineConfig } from "vitest/config";

export default defineConfig({
    test: {
        coverage: {
            enabled: true,
            thresholds: {
                lines: 90,
            },
        },
    },
});

Behavior and migration notes

this rule checks static enabled/threshold object values only
it reports once per contradictory coverage scope

ESLint flat config example

import vite from "@typpi/eslint-plugin-vite";

export default [vite.configs.strict, vite.configs.vitest];

When not to use it

Disable this rule only if your project intentionally keeps disabled coverage plus threshold placeholders in committed config.
